Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 9572, here are decompositions:

61 + 9511 = 9572
109 + 9463 = 9572
139 + 9433 = 9572
151 + 9421 = 9572
181 + 9391 = 9572
223 + 9349 = 9572
229 + 9343 = 9572
331 + 9241 = 9572

Showing the first eight; more decompositions exist.
